OCA question
Why on certain approach plates the OCA is reported and NOT on others?
I don't remember all this stuff:O Today a doubt emerged during the briefing: the OCA for our runway was increased by a Notam above the usual DA. Do we have to increase the DA accordingly or not??? Thanks |
Hi LEM!
Yes - you need to increase DA(H) accordingly. This in turn will very likely increase your operational minima for the approach & therefore also the planning minima. :( If the DA equals OCH - then OCH will not be stated seperately. If system minima are higher than OCH (CAT I = 200 ft. / OCH =, say, 153 ft.), the OCA will be stated. On old PANS-Ops approaches (prior Ops 2, methinks, but not sure at all), there was no OCA(H), but instead an Obstacle Clearence Limit OCL :zzz: Best regards fm Empty:) |
